"besides it will be good experience for you"...
That's what the recruiter tells you when you sign up for the US Army...
KAikens and Big Twinky echo my sentiments. Say a little prayer, take 10 deep breaths, and get out there are do your best. Your camera has an LCD screen on the back...after any critical sequence of shots, take a peek and make sure you are in the ballpark settings wise. What you need to guard against are sloooooow shutter speeds with combined flash exposures: in some of the programmed or scene modes, the shutter speed might dip down to slow speeds like 1/4 second....that can cause blurring from existing light, and then when the flash fires, it creates a sharp,crisp flash-lighted image which when combined with a slow shutter speed setting like 1/3,1/4,1/6 up to about 1/30 second, can cause a "ghost image". Good luck!
